Specialized Roubaix 2018–2019
Archive model 2018–2019. Probably no longer sold new. I only have the frame geometry, not the build.

Geometry ?
Specialized Roubaix geometry for model years 2018, 2019. Model years are approximate: manufacturers rarely say exactly when the geometry changed.

Future Shock (travel 20 mm) is already part of the published stack, so I sit the stem directly on it, with no more than 30 mm of cover and spacers underneath. This is an estimate: once the unit sags under your weight, the bars end up a few millimetres lower.
Bike from a listing
Buying this bike second-hand? Enter the size, stem and spacers actually on the bike to see whether it fits you.
Selling it? Fill in the details and paste the link into your listing. Buyers will see where the bars end up, based on what you enter.
How do I measure it?
Spacers: only what sits between the Future Shock unit and the stem, plus the taller 15 mm cover if fitted (0–30 mm). Length and angle are usually printed on the stem (−6° is typical, with the stem pointing down). Bar reach is on the bar manufacturer’s website. If you can’t find it, leave it at 75 mm. Spacers above the stem show how much higher the stem could still go. Leave that blank and I’ll assume it can’t go any higher.
Is it an integrated cockpit, a one-piece bar and stem? Then the stem may not be swappable. Check with the seller.
